xsl :
xsl inclulde xslt,xpath,xsl-FO
xslt is used transform the xml to the document understood by IE such as html.
Given these design goals, what are XSLT's strengths? Here are some scenarios:
Your web site needs to deliver information to a variety of devices. You need to support ordinary desktop browsers, as well as pagers, mobile phones, and other low-resolution, low-function devices. It would be great if you could create your information in structured documents, then transform those documents into all the formats you need.
You need to exchange data with your partners, but all of you use different database systems. It would be great if you could define a common XML data format, then transform documents written in that format into the import files you need (SQL statements, comma-separated values, etc.).
To stay on the cutting edge, your web site gets a complete visual redesign every few months. Even though things such as server-side includes and CSS can help, they can't do everything. It would be great if your data were in a flexible format that could be transformed into any look and feel, simplifying the redesign process.
You have documents in several different formats. All the documents are machine-readable, but it's a hassle to write programs to parse and process all of them. It would be great if you could combine all of the documents into a single format, then generate summary documents and reports based on that collection of documents. It would be even better if the report could contain calculated values, automatically generated graphics, and formatting for high-quality printing.
eg.
<?xml version="1.0"?>
<CATALOG>
<CD>
<TITLE>Empire Burlesque</TITLE>
<ARTIST>Bob Dylan</ARTIST>
<COUNTRY>USA</COUNTRY>
<COMPANY>Columbia</COMPANY>
<PRICE>10.90</PRICE>
<YEAR>1985</YEAR>
</CD>
.

.
還有附帶的XSL樣式表：
<?xml version='1.0'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl">
<xsl:template match="/">
<html>
<body>
<table border="2" bgcolor="yellow">
<tr>
<th>Title</th>
<th>Artist</th>
</tr>
<xsl:for-each select="CATALOG/CD">
<tr>
<td><xsl:value-of select="TITLE"/></td>
<td><xsl:value-of select="ARTIST"/></td>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>

We can use javascript to implement in client:
<html>
<body>
<script language="javascript">
// Load XML
var xml = new ActiveXObject("Microsoft.XMLDOM")
xml.async = false
xml.load("cd_catalog.xml")
// Load the XSL
var xsl = new ActiveXObject("Microsoft.XMLDOM")
xsl.async = false
xsl.load("cd_catalog.xsl")
// Transform
document.write(xml.transformNode(xsl))
</script>
</body>
</html>
|
In server :
<%
'Load the XML
set xml = Server.CreateObject("Microsoft.XMLDOM")
xml.async = false
xml.load(Server.MapPath("cd_catalog.xml"))
'Load the XSL
set xsl = Server.CreateObject("Microsoft.XMLDOM")
xsl.async = false
xsl.load(Server.MapPath("cd_catalog.xsl"))
'Transform the file
Response.Write(xml.transformNode(xsl))
%>
